Fig. 1 illustrates the outward appearance of the lighting device 100 of execution mode, and (a) of Fig. 1 represents that the stereogram of lighting device 100, (b) of Fig. 1 represent the plane graph of lighting device 100.Lighting device 100 possesses upper illuminating part 110, lower illuminating part 120, central blaze portion 130.Upper illuminating part 110, lower illuminating part 120, central blaze portion 130 possess the light-emitting component (LED shown in Fig. 2; LightEmittingDiode: light-emitting diode) 52 and light guide plate.Upper illuminating part 110, lower illuminating part 120, central blaze portion 130 can make the light of self-emission device to be spread by light guide plate, penetrate with making the wide scope of light thus.
In the present embodiment, under the usual ignition mode used under common illuminating state, upper illuminating part 110, lower illuminating part 120, central blaze portion 130 are all luminous.In addition, by only making central blaze portion 130 extinguish, lighting device 100 can also manifest the illumination as indirect lighting.
In addition, when using with dark illuminating state under the situations such as h.d., lighting device 100 can use with normal bright pattern at night.Night, normal bright pattern was with a small amount of electric current to one of glimmer pattern driving light-emitting component, also can realize the energy-saving of lighting device 100.In the present embodiment, only central blaze portion 130 was lighted under normal bright pattern at night.
Under usual ignition mode, the brightness of illumination apparatus 100 can carry out light modulation (adjustment) in the scope of 100% ~ 5%, thus manifest brightness.In addition, under night normal bright pattern, the brightness of lighting device 100 uses the scope of 1.5% ~ 0.5%, manifests the darkness as normal bright pattern at night thus.This darkness is alternatively can not feel to dazzle h.d. user to identify again the brightness of surrounding.Main corresponding with illumination in this " brightness ".

In addition, under night normal bright pattern, also can send signal S by " bright ", " secretly " button such as pressing remote controller 200, thus control brightness.If the duty ratio of lighting of " bright " signal then lighting device 100 becomes large and brightens, to diminish and dimmed if " secretly " signal then lights duty ratio.In addition, under usual ignition mode, each pattern of normal bright pattern at night, when the brightness for the upper limit or lower limit, the sound that lighting device 100 or remote controller 200 ring specify, user can be made thus to know, and this is the brightness of the upper limit under each pattern or lower limit.
Fig. 2 represents the circuit diagram of lighting device 100.Lighting device 100 comprises rectification circuit 20, boost chopper 30, power supply unit 40, load portion 50 and lights control part 60.
Rectification circuit 20 is made up of not shown diode bridge circuit etc., is receive alternating current (electric power) from source power supply 10 and be transformed to the circuit of direct current, can use known circuit.Boost chopper 30 is made up of not shown inductor, diode, switch element, electrolytic capacitor etc., is the circuit of boosted voltage, can uses known circuit.
Power supply unit 40 is except not shown inductor, diode, switch element etc., also comprising the electrolytic capacitor 42 be connected in parallel with the light-emitting component 52 of load portion 50, under the voltage obtained being undertaken boosting by boost chopper 30, supplying (direct current) electric power to load portion 50.Load portion 50 is made up of multiple light-emitting component 52 be connected in series, and utilizes the electric power from power supply unit 40 supply and lights.Upper illuminating part 110 shown in Fig. 1, lower illuminating part 120, central blaze portion 130 possess load portion 50 separately.
Light control part 60 and comprise control part 62, storage part 64 and acceptance division 66.Control part 62 is made up of general microprocessor, by controlling the electric power that power supply unit 40 controls to supply to load portion 50, thus controls the illuminating state of light-emitting component 52.The form that the various information such as the brightness value of lighting device 100 under various light-modulating mode can read with control part 62 is preserved by storage part 64.Acceptance division 66 receives signal (mode switching signal etc. of the switch light modulation pattern) S sent from the remote controller 200 operated by user, sends control part 62 to.
Fig. 3 is the chart representing the light-modulating mode of lighting device 100 and the relation of brightness, and this relation is kept in storage part 64 with the form that various table is such.The brightness of lighting device 100 is controlled by control part 62, and this control part 62 controls the power supply unit 40 supplying electric power to light-emitting component 52.Control part 62 is according to the chart of the Fig. 3 preserved in storage part 64, at least with usual ignition mode and light-modulating mode that night, normal bright pattern was lighting device 100, lighting device 100 is lighted, this usual ignition mode is the first light-modulating mode, and this night, normal bright pattern was the second light-modulating mode.
Usual ignition mode is the first light-modulating mode light-emitting component 52 being adjusted to the illuminating state (the second illuminating state) of 5% brightness darker than the illuminating state of this 100% brightness from the illuminating state (the first illuminating state) of the brightest 100% brightness (as the illumination that lighting device is the brightest) utilizing the maximum output of light-emitting component 52 to obtain.Light duty ratio by what controlled light-emitting component 52 by control part 62, power supply unit 40 changes the electric current supplied to light-emitting component 52, therefore brightness degree ground change like that as shown in the chart.
Night, normal bright pattern was the second light-modulating mode light-emitting component 52 being adjusted to the illuminating state (the 4th illuminating state) of 0.5% brightness darker than the illuminating state of this 1.5% brightness from the illuminating state (thirdly bright state) of dark 1.5% brightness of the illuminating state (the second illuminating state) than above-mentioned 5% brightness.
In the present embodiment, by belong to usual ignition mode (the first light-modulating mode) and the second light-modulating mode (normal bright pattern at night), the scope (scope little and larger than 1.5% than 5%) of the second illuminating state and the brightness thirdly between bright state is defined as the scope (not using brightness range) of the so-called brightness do not used.
The part of the F in Fig. 3 is amplified the figure represented by Fig. 4.As mentioned above, light-emitting component 52 brightness according to control part 62 to light the control of duty ratio and rank character change.That is, control in the mode making the brightness of light-emitting component 52 change discontinuously.At this, in the present embodiment, by bright for ratio second illuminating state under usual ignition mode and the nearest illuminating state of this second illuminating state is defined as the 5th illuminating state.In addition, by the ratio under normal for night bright pattern, thirdly bright state is dark and have and be defined as the 6th illuminating state with the illuminating state of this thirdly brightness that bright state is nearest.
In this case, from the second illuminating state in the transformation of thirdly bright state, there is the luminance difference (variable quantity) of regulation, this luminance difference is defined as the first luminance difference.First luminance difference is equivalent to variable quantity (B) in figure 3, and in the present embodiment, variable quantity (B) is 5-1.5=3.5 (%).
Further, from the 5th illuminating state in the transformation of the second illuminating state, also there is the luminance difference (variable quantity) of regulation, this luminance difference is defined as the second luminance difference.In figure 3, the second luminance difference is equivalent to variable quantity (A).The value of variable quantity (A) is such as 0.1%.
And, in the present embodiment, be at least set to that the first luminance delta (B) is than the second luminance delta (A) large ((B) > (A)).This setting means, compared with brightness when being about to the usual ignition mode before changing with pattern declines, is changing the moment of normal bright pattern at night into, the larger decline of brightness generation from usual ignition mode.
If when (A) and (B) are roughly equal, then user is likely difficult to grasp lighting device 100 when changes normal bright pattern at night into from usual ignition mode.But make change during Mode change increase compared to the change before Mode change like that by brightness change described above, user can grasp lighting device 100 clearly changes normal bright pattern at night into from usual ignition mode.Thus, following confusion can be prevented: although user operation remote controller 200, and do not know whether the pattern of lighting device 100 changes normal bright pattern at night into from usual ignition mode.Therefore, the lighting device 100 of present embodiment improves convenience, the use sense of user.
Further, in the transformation of the 6th illuminating state from thirdly bright state, also there is the luminance difference (variable quantity) of regulation, this luminance difference is being defined as the 3rd luminance delta.In figure 3, the 3rd luminance difference is equivalent to variable quantity (C).The value of variable quantity (C) is such as 0.2%.
And, in the present embodiment, as preferred setting, be set to that the first luminance delta (B) is greater than the 3rd luminance delta (C) ((B) > (C)).Changed by this brightness, user more clearly can grasp lighting device 100 changes normal bright pattern at night into from usual ignition mode.Therefore, the lighting device 100 of present embodiment further increases convenience, the use sense of user.
Fig. 4 is an execution mode of brilliance control, and Fig. 5 represents another execution mode of brilliance control.In the present embodiment, control part 62 controls the brightness of light-emitting component 52 to make the mode be provided with during the extinguishing of zero luminance between usual ignition mode and night normal bright pattern.According to the present embodiment, extinguish between lighting device 100 short-term, therefore user more clearly can grasp lighting device 100 and changes normal bright pattern at night into from usual ignition mode.Thus, following confusion can be prevented: although user operation remote controller 200, and do not know whether the pattern of lighting device 100 changes normal bright pattern at night into from usual ignition mode.Therefore, the lighting device 100 of present embodiment improves convenience, the use sense of user.The luminance delta (A) of the execution mode of Fig. 5, (B), (C) also can determine in the same manner as the luminance delta of Fig. 4 (A), (B), (C).
In addition, the pattern of the brightness shown in Fig. 3, Fig. 4, Fig. 5 is kept in storage part 64, reads preserved pattern by control part 62.Also can prestore multiple patterns by storage part 64, select any one pattern to enable user.
In addition, under the usual ignition mode of Fig. 3, Fig. 4, Fig. 5, the brightness of light-emitting component 52 can be controlled as follows: the degree of the no matter brightness of lighting device 100 is how, if user press remote controller 200 night Chang Liang button, control part 62 just changes normal bright pattern at night into immediately.
In addition, control part 62 can control lighting device 100 as follows: change into neither usually ignition mode neither night normal bright pattern, after brightness is essentially the extinguishing pattern of zero, reproduce brightness during normal bright pattern at last night.Such as, under night normal bright pattern, wish that the user operation remote controller of zero luminance changes extinguishing pattern into make lighting device 100.When remote controller reverts to normal bright pattern at night to user again, can light with brightness before.Storage part 64 stores last brightness during the normal bright pattern at night before extinguishing pattern, reads this brightness at night when normal bright pattern starts again by control part 62, can carry out this control thus.
In addition, under the extinguishing pattern that brightness is essentially zero, in general supply the electrolytic capacitor 42 not accumulated charge (not charging) in the power supply unit 40 of electric power to light-emitting component 52.In addition, under the light-modulating mode of the power saving bright pattern as normal in night, the duty ratio of lighting that light-emitting component 52 is lighted is set to low value.This means that the charging duty cycle be responsible for electrolytic capacitor 42 charging is also low, charging will spend official hour.
Therefore, in lighting device in the past, when user carries out the transition operation changed from the light-modulating mode of the power saving of extinguishing pattern to bright pattern as normal in night, the starting to light of light-emitting component 52 also needs official hour, it is contemplated that out thus and such as device can be brought whether to there occurs the such confusion of fault to user.
Fig. 6 is the sequential chart of the relation of the illuminating state representing charging duty cycle, light duty ratio and lighting device, and (a) of Fig. 6 represents the sequential chart in above-mentioned lighting device in the past.It is desirable to, based on the operation by user from the mode switching signal from extinguishing pattern to normal bright pattern at night that remote controller 200 sends, come into effect the charging duty cycle starting to charge to electrolytic capacitor 42, start lighting under normal bright pattern at night together with the beginning timing of lighting duty ratio.But, as shown in (a) of Fig. 6, due to above-mentioned reason, t time of delay from the regulation of receiving mode switching signal to lighting can be produced
g1.Particularly, time of delay t
g1than considering the performance (charging interval) of electrolytic capacitor and the charging duty cycle period t that obtains
1(such as 1.5 seconds) are long.
(b) of Fig. 6 represents the sequential chart of the lighting device 100 of present embodiment.In order to remove problem as above, in the present embodiment, control part 62 is according to the charged state of electrolytic capacitor 42 of power supply unit 40 supplying electric power to load portion 50, the electric power supply controlling to be undertaken by power supply unit 40, and control the charging duty cycle of electrolytic capacitor 42, light-emitting component 52 light duty ratio.
Under the extinguishing pattern that brightness is essentially zero, electrolytic capacitor 42 is in not by the uncharged state of charging.Acceptance division 66 receives mode switching signal from from extinguishing pattern to normal bright pattern at night from remote controller 200 in this condition, meanwhile control part 62 controls power supply unit 40, with the duty ratio of lighting of regulation, electrolytic capacitor 42 is promptly charged official hour, charge in advance thus, thus remove startup (lighting) delay.Particularly, light duty ratio for charging duty cycle in the upper limit of this power supply unit 40 with night under normal bright pattern, start to charge to electrolytic capacitor 42.But not necessarily the duty ratio of lighting of the upper limit under normal for night bright pattern will be set as charging duty cycle, what both can be greater than the upper limit under normal bright pattern at night lights duty ratio, and what also can be less than the upper limit under normal bright pattern at night lights duty ratio.As long as control part 62 controls power supply unit 40 as follows: starting from the extinguishing pattern of zero luminance after the second light-modulating mode transformation, with than after changing the second light-modulating mode into light duty ratio large light duty ratio for charging duty cycle, start to charge to electrolytic capacitor 42.
Its result, with t time of delay of the startup (lighting) shown in (a) of Fig. 6
g1compare, become shorter t time of delay
g2, thus relaxed the delay of startup (lighting).Such as, the charging of electrolytic capacitor 42 is with t time of delay than more than 1.5 seconds
g1t time of delay of short 1 second
g2complete, start lighting of light-emitting component 52.And at 0.5 second (t
2=t
1-t
g2) after, change lighting (brightness stored in storage part 64) under normal bright pattern at night into.Particularly, this with night normal bright pattern the upper limit brightness, namely 1.5% brightness light t
2second (" time uncharged " with reference to (b) of Fig. 6).
On the other hand, changing into from usual ignition mode under the such situation of normal bright pattern at night, also there is the situation (be " during full charge " by these state unified definitions) that electrolytic capacitor 42 is charged to quota or is charged to level to a certain degree.
In this case, acceptance division 66 receives the mode switching signal (such as from usual ignition mode to the mode switching signal of normal bright pattern at night) from remote controller 200, meanwhile control part 62 controls power supply unit 40, makes light-emitting component 52 light official hour with the duty ratio of lighting of regulation.At this, with night, t is lighted in brightness, i.e. 1.5% brightness of the upper limit of normal bright pattern
3second (in this case 1.5 seconds) (" during full charge " with reference to (b) of Fig. 6).
Namely, in lighting device in the past, when electrolytic capacitor 42 is charged to the level to a certain degree, duty ratio is lighted if directly start, light-emitting component 52 then can be made with the Intensity LEDs corresponding to the degree of charging, thus likely occur because of problems such as the flickers that the brightness at a flash causes.But, in the present embodiment, changing night into and adjusting before normal bright pattern lighting time and the brightness of light-emitting component 52, the flicker that the brightness because of a flash causes, the delay of lighting can reduced thus, thus light without incongruity.
In the present embodiment, light-emitting component 52 is at t
2=0.5 second, t
3in the scope of=1.5 seconds such time with night normal bright pattern the brightness (specifically 1.5%) of the upper limit luminous.If this time and brightness, then user is not easy to feel inharmonious.That is, when bright Mode change normal to night from extinguishing pattern, t
2=0.5 second, therefore from after remote controller 1 second afterwards just with night normal bright pattern the upper limit light, therefore user is not easy to feel inconsistent.In addition, when bright Mode change normal to night from usual ignition mode, can from night normal bright pattern the brightness of the upper limit to normal bright Mode change at night, therefore switching to the flicker that there is not the brightness because of a flash night after normal bright pattern and cause, user is not easy to feel inharmonious.
In addition, as another execution mode, also the time of lighting duty ratio before transformation can be measured according to the lighting time of the usual ignition mode before changing normal bright pattern at night into by control part 62, the charging interval of electrolytic capacitor 42 is supposed, with the charging adjusted for lighting and the time of lighting duty ratio based on this.
In addition, the lighting device 100 of present embodiment has the system of upper illuminating part 110, lower illuminating part 120, these three light sources of central blaze portion 130, but is not particularly limited in this mode, and the lighting device for a system also can apply the present invention.In addition, to be not necessarily limited under night normal bright pattern only central blaze portion 130 and to light such control, also can realize normal bright pattern at night by upper illuminating part 110, lower illuminating part 120, these three systems of central blaze portion 130.In addition, the physical circuit of lighting device 100 is also not limited to the circuit shown in Fig. 2.
In addition, in the present embodiment, the first light-modulating mode is corresponding with usual ignition mode, and the second light-modulating mode is corresponding with normal bright pattern at night.But the first light-modulating mode, the second light-modulating mode are not limited to this pattern.Such as, also can be that the first light-modulating mode is full ignition mode, and the second light-modulating mode is battery saving mode.In addition, also can also set the 3rd light-modulating mode except the first light-modulating mode, the second light-modulating mode, to three light-modulating mode application the present invention.
In addition, the present invention is not limited to above-mentioned execution mode, can suitably be out of shape, improvement etc.In addition, as long as the material, shape, size, numerical value, form, quantity, allocation position etc. of each structural element in above-mentioned execution mode can realize the present invention, it is arbitrary and not circumscribed.In addition, the shape of the detail section of each component also can be different from the shape being shown in each figure in above-mentioned explanation.
